January 1 TCP/IP

On January 1, 1983, 400 computers on ARPANET, the predecessor of the Internet, hooked up to each other using Transmission Control Protocol/Internet Protocol (TCP/IP).

Twenty-five years later, TCP/IP powers the modern Internet. Google marks this important anniversary with a very special Google Doodle.

The confetti at the bottom forms the words SYN SYN/ACK ACK — synchronize, synchronize/acknowledge, acknowledge — the three-way handshake of a TCP/IP connection.

Twenty-five years after that first historic handshake, the world is connected. May 2008 bring you even more heartfelt handshakes and meaningful connections.
